Planet frog tadpols

I got a Planet Frog habitat and two tadpoles. One of them is a frog now. It's been about 4weeks since I got the tadpoles. They're about an inch long. One's name is Fred and the other one's name is George. They are leopard frogs. As tadpoles they eat specialised tadpole food. As frogs they eat crickets and small chunks of worm.
